## Summary

This document proposes to adopt a new airworthiness directive (AD) that would apply to all Industrie Aeronautiche e Meccaniche (I.A.M.) Model Piaggio P-180 airplanes. The proposed AD would require inspecting both (left and right wing configurations) environmental control system bleed tubes for damage, leakage, and a correct gap between the tube and wing lower panel crossing area, inspecting the wiring and surrounding structures for damage, and correcting any discrepancies found. The proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Italy. The actions specified by the proposed AD are intended to prevent thermal expansion from causing leakage of an environmental control system bleed tube because of improper installation, which could result in deterioration of the electrical wiring and the surrounding structure.
